Unlikely, as most other countries have announced their headliners. Big question is who will be the third headliner in the UK. Currently the dead certs are Queen with Adam and Faith No More. Third headliner seems to be between Kiss, GN'R and Green Day - with Kiss appearing to be stronger rumour right now due to GN'R dates for the UK being at the end of May (Manchester on 29, and rumour of London on 30 & 31).

Wouldn't you just love it if Kiss was on the same bill with Adam performing with Queen.....I wonder how Gene Simmons would enjoy that crow he would be eating

With a quarter of a century having since passed, rock legends QUEEN are to return to play a second concert at the venue that provided them with the setting for one of their biggest and most historic concerts.

QUEEN’s Brian May and Roger Taylor have confirmed the band will headline the second day of SONISPHERE appearing on the APOLLO stage on Saturday July 7. KNEBWORTH was the setting for QUEEN’s final concert with Freddie Mercury in August 1986.

May and Taylor also confirmed that for this very special event they will be joined by US singer-songwriter ADAM LAMBERT.

The potent chemistry between QUEEN and Lambert broke the surface when at the invitation of Brian May and Roger Taylor, Lambert joined them for the closing showcase at the recent MTV Europe Awards where QUEEN were present to collect their Global Icon award.

Says Brian May: “Judging by my incoming mail, this decision will make a lot of people very happy. It’s a worthy challenge for us, and I’m sure Adam would meet with Freddie’s approval! And what better place to revisit, and walk those emotional paths than Knebworth? It will be a rush.”

“Earlier on there were rumours of us splitting up, but I mean – f*** ‘em – how can you split up when you have an audience like this.” Freddie Mercury. Knebworth Park, August 9, 1986

With a quarter of a century having since passed, rock legends Queen are to return to play a second concert at the venue that provided them with the setting for one of their biggest and most historic concerts.

Queen’ Brian May and Roger Taylor today confirmed the band will headline the second day of this year’s Sonisphere Festival appearing at the festival home ground Knebworth Park, Stevenage, on Saturday July 7.

Knebworth was the setting for Queen’s final concert with Freddie Mercury in August 1986.

May and Taylor also confirmed that for this special one-off concert they will be joined by US singer-songwriter Adam Lambert.

Since first encountering each other during American Idol Season 8 in May 2009 where Lambert joined the band to perform We Are the Champions the two have repeatedly hinted at a future collaboration, most recently with Taylor telling Billboard Magazine "He (Adam) has grown into a really great performer with an astonishing voice with a range that's great. We would like to work with him again. There's nothing signed just yet but …it could be very exciting."

After their brief meeting on American Idol, the potent chemistry between Queen and Lambert finally broke the surface when at the invitation of Queen’s Brian May and Roger Taylor Lambert joined them for the closing showcase at the recent MTV Europe Awards where Queen were present to collect their Global Icon award.

Their eight minute MTVE set ignited an immediate reaction across the internet with social network sites buzzing with excitement and campaigning for a more formal union between Queen and Lambert. The Sonisphere 2012 Knebworth stage will at last provide an eager public the opportunity to see May, Taylor and Lambert delve deeper into exploring their very evident artistic appreciation of one another.

Says Brian May: “Judging by my incoming mail, this decision will make a lot of people very happy. It's a worthy challenge for us, and I'm sure Adam would meet with Freddie's approval! And what better place to revisit, and walk those emotional paths than Knebworth? It will be a rush.”

Lambert adds: “I'm completely in awe of the Queen phenomenon. The thought of sharing the stage for a full set is so beautifully surreal. I'm honoured to be able to pay my respects to Freddie's memory. He's a personal hero of mine and I am deeply grateful for the chance to sing such powerful music for fans of this legendary band. I know the evening will be a huge milestone for me, and with the support of Brian, Roger and the rest of the band I know magic will be on display.”

Queen’s previous performance at Knebworth Park, close on twenty-six years ago, August 9, 1986, was set up to be the glorious last stop for the band’s monstrously successful Magic Tour which had spread out across Europe over eight weeks of that summer. Over a million people had already paid to see them.

Now riding one of the highest crests in their career, Queen drew a record crowd of 120,000, their biggest ever UK audience. Coming on the back of two stunning shows at Wembley Stadium - to this day regarded as among their finest performances - anticipation was high.

Queen delivered the goods, winding up the crowd by arriving above their heads in a custom decorated helicopter, and then going on to perform a Queen textbook set to a deliriously enthusiastic audience, winding up with an emotional ‘God Save the Queen’ and Freddie wishing his audience ‘sweet dreams’.

What no-one in that Knebworth Park audience, and as far as we know, not even the band could anticipate that day, was that a new chapter in Queen’s history was being written: after more than 700 concerts together, what was taking place was the very last live concert of Freddie Mercury with Queen.

With the exception of an appearance in 1988 with Spanish operatic soprano Montserrat Caballe to launch Barcelona’s successful bid for the 1992 Olympic Games performing their duet ‘Barcelona’, Mercury would never again be seen performing to a public audience.

On what will undoubtedly rate as one of this summer’s most highly anticipated and emotionally charged concerts Queen’s Roger Taylor says: "I remember Knebworth as being the most incredible gig, with the most amazing audience and the sound on stage was utterly perfect. It was a fitting last stand before a live audience for Freddie. It will be a real challenge to complete the circle by returning with Adam."
